C. B. GILMORE WINDOW ATTACHMENT Filed June 24, 1927 ./mmm? 2 Sheets-Sheet 2 Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE CHARLES B. GILMORE, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO FORGING & MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORFORATION OF ILLINOIS WINDOW ATTACHMENT Application filed June 24,

My'invention relates to a curtain raising and lowering device and has for its principal purpose the provision of a device for raising and lowering curtains in response to the raising and lowering of a window sash. One object of'my invention is to provide a simple and efficient mechanism for accomplishing the above function, which shall be cheap, simple to manufacture, sturdy in construction and eliicient in use. Another object is the elimination so far as possible, of guiding devices on the window frame. Other objects will appear from time to time in the course of the specilication and claims.

I villustrate my invention more or less diagrammatically in the accompanying drawings, wherein# Figure l is a front elevation of a window of my device in position;

Figure 2 is a. vertical section on the line 2-2 of Figure 1;

Figure 3 is a section on the line 3 3 of Figure l;

Y Figure 4c is a section on the line 4 4 of i Figure 3 Figure 5 is a perspective view of a detail;

Figure 6 is an enlarged front elevation of the device with parts in different positions and'partly broken away; and

Figure 7 is a section on the line 7-7 of Figure 6.

Like parts are indicated by like symbols throughout the specification and drawings.

Referring to the drawings, A indicates any suitable window frame having the upper sash A1 and the lower sash A2 with the side members A3.

B indicates any suitable curtain rod or supporting structure from which depends the. curtain B1. The curtain is herein shown as having a hem or doubled portion intermediate top and bottom as at B2, through which passes the rod B3 the ends of which are. secured to the lifting mechanism below described. It Will be observed that the lower edge B4 of the curtain normally depends to o'r beneath the window sill A4. l j Y.

Mounted at the upper corners of the sash side members A3 are the outwardly projecting shields C herein shown as including. a gen- 1927. Serial No. 201,114.

erally semi-circular body provided with the laterally extended flanges C1 which may be Screwed or bolted to the window frame. The body C is further provided with a iange C2 extending in the opposite direction.

Contained within the housing or shield thus formed is a support member including a flange D which underlies the flange C1 above described and is held to the sash frame by the same securing means. Outwardly projecting from the sash is the support portion D1 through which passes a pivoted member' D2. D3 indicates a stop notch on the upper side of said support and D4 a laterally extending stop lug on the lower side thereof.

Mounted upon the pivot D2 is a lever E at the outer end of which is a notch El in which is seated the end of the rod B3, which v may be squared or flattened or notched as at B3 to penetrate said notch. E2 is a pivoted locking member adapted to close said notch, and E3 is a stud or projection thereon, adapted to engage the notch E1 to hold the member E2 against unintended movement. rlhe pivot end of the lever is enlarged as at E4 and the the enlargement is provided with an arcuate slot E3 through which passes the previously described stop lug D4. EG is a laterally projecting lug formed beyond the arcuate slot E3 at the pivot end of the lever.

Mounted on the lever is the dog G pivoted thereto as at G1 and provided with a laterally extending lug G3 adapted to engage the stop slot or notch D3, above described. G3 is an upset portion on the lever adapted to limit the rearward movement of the dog Gr.

Mounted `on the window frame, adjacent the normal position of the above described mechanism when the sash is lowered is the member shown in detail in Figure 5.

H indicates a flat body portion thereof provided with the screw or bolt holes H1, whereby it may be attached to the window frame. Projecting from the lower inner side thereof is the arcuate lug H2 and projecting outwardly from vthe opposite side thereof is the rectilinear lug H3 provided with the inclined end portions H4 H3, saidlug and its end portions being inciined across the vertica path of movement of the sash.

It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and dispositi-on of parts without departing from the spirit .of my invention. I Ytherefore wish my drawings and .description to be taken as in a. broad sense illustrative and diagrammatic rather than as limiting me to my specific Shelving.

The ruse and operation of my invention are as follows:

When the window is closed as shown in Figures l and 2, the curtain 'B1 hangs in relaXed positi-on, the parts being so pro ortionedtihat the rod V,B3 does not lift or fold the l.curtain at all. At such time the edge of the curtain hangs 'below the edge of the window sill, when the proportion of parts is as herein shown. VV-hen :the sash is lifted the inner ends `oat the levers E engage the arcuate .cams H2 and the levers are therefore rotated about their .pivots to the position shown in Figure 7. Vhen they reach such position the .dogs .G .drop into .the slots D3 and prevent the levers from rotating baci; into horizontal position. Unless tampered with the `levers will remain in raised position until the sash is again lowered, and .the curtain is folded and raised, as sli-own in .dotted li-ne in F igure 2. JIhe result is to lift .the lo-.wer edge .of .the vcurtain above .the lower edge of the sash. rI'his prevents thecurtain from blowing outof the window and prevents it from. being moistened by rain .or dirtied by inhlowing dust.

lvl-ien the .sash is again lowered the .dog (al is engaged and lifted by the arcuate lug H2 .and the lever `is permitted to rotate Ainto the lowered .position shown in Figure 3. The lug D* in .the varcuate slot E limits the movement Aof the lever, the lever not being per:- mitted .to rotate, in .the form herein shown, below a substantially horizontal position. i

It is important that .when the curtain descends both levers shall rotate in unison. If for ,any reason one ol the levers is rotated into lowered position while the sash is raised, its lug EG engages the inclined lug H3 of the member H and .the lever is rotated into a raised position just -fbefore .the sash reaches its lower position. Immediately after the lever has been raised 4by such .contact with the tlange H3 .the dog Gr is enga-ged by the lug D3 .and 4b ojth levers .rota-te in unison to the lower position.

lI claim l. In yan apparatus including a frame, a sash movable -in the trame, and curtain raisingmeansgassociated with the sash, the combination with the curtain raising means o f mea-ns `carried by the Asash to .retain lthe curtain-raising means inraised position.

In an apparatus including a frame, a sash movable in the frame, curtain -raising means associated with the sash and actuating -n ieans for said lcurtain raising means, mounted 'on the window frame, the 4combination with the curtain raising means of means carried bythe sash to retain the curtain raising means in raised position after the curtain raising means have been actuated.

4. In an apparatus including a frame, a

5. In an apparatus including a frame, a sash movable on the frame .and a curtain raising lever pivoted to the sash,the combination with the .curtain raising lever of means carried by the sash .to retain the lever in raised position, said means including a stop element mounted .upon the sash, and a .stop engaging member associated with the lever. v

6. In an apparatus including a frame, a sash movable in the frame, and a .curtain raising element in pivotal relation with the sash, the combination with the curtain raising element of means carried .the sash for retaining it in raised position, and means adapted, when the retaining element becomes disengaged, to raise said curtain raising element upon downward movement of the sash.
